This patch ensures that we only update the external image resource for
WebGPU when there has been an actual change for the resource. In order
to guarantee this, we wait for the present to complete, and only then
issue the update. WebRenderBridgeChild::SendResourceUpdates will also
trigger a frame generation if any resources were changed, which means we
don't need to trigger a paint on the frame itself anymore.
Note that we still have a race condition when we write into the
MemoryTextureHost while in PresentCallback, and the renderer thread may
be accessing the pixel data to upload to the GPU.

This is necessary for when WebGPU objects are accessed from a worker
thread instead of the main thread. It should be otherwise a
non-functional change.

Similar to PWebGL, we want PCanvasManager to manage the PWebGPU
protocol. This will allow us to reuse the machinery that works for both
the main thread, and arbitrary worker threads to create PWebGPU
protocols.
For now, the only owner is still the main thread, so it should work very
similarly as to how it does with PCompositorBridge.
This patch also introduces some quality of life changes, such as making
the protocol ref-counted, and avoiding respinning the wheel for
CanSend() for IPDL actors.

This patch separates out new helper methods that are shared with the
OffscreenCanvas display integration in a later part in this series.
It also standardizes on SupportsWeakPtr/WeakPtr instead of mixing in C++
standard library versions.

we were doing UTF16 -> ASCII null term -> UTF8, and we were losing information on the way.
Now we go UTF16 -> UTF8 -> UTF8 null term
Also, we no longer accept SPIR-V

This update makes wgpu a vendored dependency instead of having it in gfx/wgpu.
## Notes
It relies on https://phabricator.services.mozilla.com/D123157
It has a quirk related to OpenGL ES backend. Previousy, we manually had to disable GL backend
in order to avoid vendoring WASM dependencies in. This time, manual editing is more complicated,
so instead this change adds a few cargo patch lines to point WASM dependencies to dummy projects.
The update also totally removes SPIRV-Cross, since the latest `wgpu` doesn't depend on it any more.
The compiled binary size for Gecko should improve with this.

This *mostly* gets us the latest WebIDL API of WebGPU. There is a few limits we are missing, and maybe some things I didn't notice.
But it gets us the new `GPUCanvasContext`, `GPUSupportedLimits`, and `GPUVertexStepMode`.
